Hendrik Christoffel "Henk" van de Hulst (Utrecht, Nov 19, 1918 – Leiden, Jul 31, 2000) was a Dutch astronomer and mathematician.
In 1944, while a student in Utrecht, he predicted the existence of the 21 cm hyperfine line of neutral interstellar hydrogen. After this line was discovered, he participated, with Jan Oort and Alex Muller, in the effort to use radio astronomy to map out the neutral hydrogen in our galaxy, which first revealed its spiral structure.
He spent most of his career at the University of Leiden.
